Hertel 45674421 Chucking Reamer 0.0485 in Solid Carbide

Product Description

The HERTEL 45674421 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a reamer diameter of 0.0485 inches and an overall length of 1.5 inches, this tool is built for small-bore work where dimensional accuracy is critical. The straight shank seats cleanly in standard chucks, and the bright polished finish reduces friction during cutting. Four straight flutes with right-hand cutting direction make this reamer well suited for CNC and manual drilling operations requiring consistent bore geometry and smooth surface finish.

This reamer is used in metalworking and precision machining environments, including job shops, tool rooms, and production floors. It is appropriate for through-hole and blind-hole finishing in a range of ferrous and non-ferrous materials. The 0.375 inch flute length handles material removal in shallow-depth bore applications. Machinists and tool-and-die professionals installing or refurbishing components that require tight hole tolerances are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 0.0485 inch diameter for small-bore precision finishing
• Bright polished finish reduces built-up edge and cutting friction
• 4-flute straight configuration for accurate, chatter-resistant cutting
• Right-hand cutting direction compatible with standard spindle rotation
• Straight shank for secure seating in collet chucks and drill chucks

Compatibility

Designed as an OEM-style chucking reamer for use in straight-shank chuck toolholders on CNC machining centers, knee mills, and drill presses requiring small-diameter precision bore finishing.

Installation Notes

Chucking reamers of this diameter should be installed by qualified machinists familiar with small-bore tooling. Ensure the machine spindle is fully stopped and the chuck is secure before installing or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not use this tool to remove excessive stock — reamers are finishing tools and should follow a properly sized drill or boring operation.
